Monetize Anonymous & Aggregate Banking Data
Problem
Valuable banking data needed to be anonymous & unified
•  Bank possesses data that indicates larger macro-economic trends, which can be
monetized in secondary markets
•  Regulations and company policies protect customer privacy
•  Data sets are isolated in legacy silos controlled by LOBs
•  IT challenged by joining data while guaranteeing anonymity
Solution
Cross-bank data lake for aggregate data with secure access
•  Multiple data sets abstracted from source platforms
•  Single point of security & privacy for de-identification, masking, encryption,
authentication and access control
•  Mortgage bankers, consumer bankers, credit card group and treasury bankers have
access to the same cross-sell data
•  Interoperability with partners SAS, R, RedHat & Splunk
•  Economies of scale for compression & archiving data
•  Significant reduction in storage costs from prior platforms
Creating Opportunity
Data: Structured,
Clickstream, Social &
Unstructured
Banking
One of the largest US banks

Insurance Data Lake to Manage Risk
Problem
Challenges merging new & old data hamper analysis
•  Traditional and newer types of data were both growing quickly but were difficult to
combine in the EDW
•  “Schema on load” requirements of EDW platform limited ingest of some data with
significant predictive power
•  Company missed data-driven ways to serve customers
•  Process of separating legitimate from fraudulent claims created “needle-in-a-
haystack” problem
Solution
Common platform for all types of data improves up-sell and reduces fraud
•  “Schema on read” Hadoop architecture means that more data sources can be
easily ingested to enrich predictive analytics
•  Agents use big data insights to determine the best action for valued customers and
recommend those in real-time
•  Claims analysts and underwriters process streaming data to quickly flag fraud risks
and fast-track legitimate claims
Creating Opportunity
Data: Structured,
Clickstream, Server Log

Maintaining SLAs for Equity Trading Information
Problem
Meeting 12 millisecond SLAs for “ticker plant”
•  Daily ingest: 50GB server log data from 10,000 feeds
•  Four times daily, this data is pushed into DB2
•  Applications query this data 35K times per second
•  70% of queries are for data <1 year old, 30% for >1 year old
•  Current architecture can only hold 10 years of trading data
•  Growing volume puts performance at risk of missing SLAs
Solution
Meeting SLAs with confidence
•  HBase provides super-fast queries within SLA targets
•  ETL offloading to Hadoop allows longer data retention, without jeopardizing fast
response times
Improving Efficiency

3 Problems For Sharing Data Across Clusters
LAN / WAN

31
•  Require Continuous Availability
–  SLA’s, regulatory compliance
•  Require HDFS to be Deployed Globally
–  Share data between data centers
–  Data is consistent, not eventual
•  Ease Administrative Burden
–  Reduce operational complexity
–  Simplify disaster recovery
–  Lower RTO/RPO
•  Allow Maximum Utilization of
Resources
–  Within the data center
–  Across data centers
Enterprise-Ready Hadoop
Characteristics of Mission-critical Financial Applications

32
Single Standby
•  Inefficient utilization of resource
–  Journal Nodes
–  ZooKeeper Nodes
–  Standby Node
•  Performance Bottleneck
•  Still tied to the beeper
•  Limited to LAN scope

–  ZooKeeper Nodes
–  Standby Node
•  Performance Bottleneck
•  Still tied to the beeper
•  Limited to LAN scope

•  All resources utilized
–  Only NameNode configuration
–  Scale as the cluster grows
–  All NameNodes active
•  Load balancing
•  Set resiliency (# of active NN)
•  Global Consistency

34
Standby Data Center
•  Idle Resource
–  Single Data Center Ingest
–  Disaster Recovery Only
•  One way synchronization
–  DistCp
•  Error Prone
–  Clusters can diverge over time
•  Difficult to scale > 2 Data Centers
–  Complexity of sharing data
increases

–  Clusters can diverge over time
•  Difficult to scale > 2 Data Centers
–  Complexity of sharing data

Active / Active
•  DR Resource Available
–  Ingest at all Data Centers
–  Run Jobs in both Data Centers
•  Replication is Multi-Directional
–  active/active
•  Absolute Consistency
–  Single HDFS spans locations
•  ‘N’ Data Center support
–  Global HDFS allows appropriate
data to be shared
What’s in a Data Center

37
•  Data is as current as possible (no
periodic synchs)
•  Doesn’t require monitoring and
consistency checking
•  Virtually zero downtime to recover
from regional data center failure
•  Regulatory compliance
Use Case: Disaster Recovery

38
•  Ingest and analyze anywhere
•  Analyze everywhere
–  Fraud detection
–  Equity trading information
–  New business
–  Etc…
•  Backup data center(s) can be used
for work
–  No idle resources
Use Case: Multi-Data Center
Ingest and multi-tenant workloads

39
•  Mixed Hardware Profiles
–  Memory, disk, CPU
–  Isolate memory-hungry
processing (Storm/Spark) from
regular jobs
•  Share data, not processing
–  Isolate lower priority (dev/
test) work
Use Case: Heterogeneous Hardware
In-memory analytics

The difficulty realizing the data lake…

46
Periodic Synchronization
DistCp
Hacks currently in use
•  Runs as MapReduce
•  DR data center is read-only
•  Over time, Hadoop clusters
become inconsistent
•  Manual and labor-intensive
process to reconcile differences
•  Inefficient use of the network

47
Parallel Data Ingest
Load Balancer, Flume
Hacks currently in use
•  Hiccups in either of the Hadoop
clusters causes the two file
systems to diverge
•  Potential to run out of buffer when
WAN is down
•  Requires constant attention and
sys-admin hours to keep running
•  Data created on the cluster is not
replicated
•  Use of streaming technologies
(like flume) for data redirection are
only for streaming
